Title:
A MOBILE TERMINAL PREVENTING TEMPERATURE RISING OF USER-SENSITIVE SURFACE
Document Type and Number:
WIPO Patent Application WO/2009/003411
Kind Code:
A1
Abstract:
A mobile terminal preventing temperature rising of user-sensitive surface
and a display device and a heat dissipating device of electronic product based
on satisfaction of user, the mobile terminal preventing temperature rising
of user-sensitive surface comprises a user-sensitive surface and a PCB, a heat
insulating layer is arranged between the user-sensitive surface and the PCB;
the display device comprises a display screen, a case with vacuum space is arranged
back of the display screen. The technical solutions control the temperature
of the user-sensitive surface during operating process efficiently, raise
satisfaction of user, and reduce the probability of complaint for heating. The
heat dissipating device of electronic product based on satisfaction of user
comprises a heat conducting case surrounding a PCB and a heating component. A
heat insulating structure is arranged on user contact area of the heat conducting
case to depress the temperature of the surface of the area. An embodiment of the
invention reduces the mental impression of overhigh temperature caused by heat
dissipation sensed by user, who contacts the heat dissipating device utilized
as a case or part of a case of an electronic product, by the heat insulating structure
arranged on the user contact area of the heat conducting case to depress the temperature
of the surface of the area. Heat conducting case in the heat insulating structure
can be used as a heat dissipator to control temperature rising of the component
and misproportion of the temperature of the surface effectively.
